Planets were not created out of the big bang, other than possibly some gas giants that formed around the first cycle superstars. The Big bang created only hydrogen, helium, and trace amounts of lithium - none of the materials normally associated with a planet.
Planets came later, when the first cycle stars went Supernova, fusing heavier elements into existence, and exploding these elements out into space.
Planets are round because of gravity's force. You'll notice that even in our solar system. asteroids smaller than Sedna do start to look irregular. Once you get over a 600 km circumference, gravity starts to dictate the object's shape... that's why stars are round too.

Planets were not created by a big bang! And they are not round as well. Earth is partially flat near the poles.

Planets were not created out of the Big Bang. Planets are created from the leftovers of star formation.

Because the big bang theory is incorrect, sort of, sorry, I am bringing on different subjucts, the answer is because only a few planets were around during the "Big Bang"

We began as a micro-micro organism that alter into accrued in the extreme density center of the universe before the super bang, that micro organism later stepped forward because of the modifications in its ecosystem (the two that, or merely most of the climate have been in the middle, they bonded after the bang and thank you to the ecosystem of what could be earth stepped forward into microorganisms and "quickly" stepped forward into the beings all of us be attentive to and love immediately). It replace into all purely a handy sequence of accident that each thing ended up as that's, a 0.000000001 hazard that merely looked as though it could happen. How did all of us get into the planet with oxygen? nicely, it replace into the only place our ancestor unicellular organisms thrived on (that all of us be attentive to of) so it could purely make experience that we are all on the earth. One does not could desire to be an Atheist to respond to that, I merely take place to be one.

they were not round when they were formed. after their formation. thy became roung becuse the gases in the atmosphere rubbed against it each time giving it a roud like shape however this process took millions of years.

most f the planets were fluids. hence they got their round shape

It's due to the gravitational pull: the ultimate binding force in the endless universe....

its because.....
we all know tat the planets revolve around the sun.....
and wen it does so, dust particals

they are not round they are actually flat at the poles look at our earth only!!!THEY ARE IN IRREGULAR SHAPE DON"T THEY HAVE DIFFERENT LANDFORMS LIKE MOUNTAINS AND HILLS.!!!!!!!
